Sheet Metal Fabrication

Laser-cut, bent and welded sheet metal parts — enclosures, brackets, panels and chassis — supplied alongside the machined parts that go inside them. Fabricated by a partner plant we have worked with for years; specified, inspected and delivered by us.

Straight answer

We do not run a sheet metal line. Here is what we do instead.

GY is a machining shop. Sheet metal work is done by a fabrication plant we have used for years and whose quality we know — we say this up front because a buyer finds out eventually, and it is better heard from us.

What you get from us is one supplier and one order. We review the flat pattern and bend reliefs against your drawing before anything is cut, we inspect every batch when it comes back, we assemble sheet metal and machined parts together where the design calls for it, and we ship it all on one date with one packing list. If a bracket does not fit the housing we milled, that is our problem to fix, not a conversation between three companies.

Processes

What the partner plant does, and what we check

Laser cutting

Fibre laser cutting of steel, stainless and aluminium sheet. Clean edges, tight nesting, no tooling — so a one-off costs the same per part as a hundred. We check flat-pattern dimensions and hole positions on the first sheet. Laser cutting →

Bending

CNC press-brake forming. Bend angle and flange length are where sheet metal parts go wrong; we call out bend radii and reliefs on the drawing before cutting and gauge the first bent part against it.

Welding and hardware

TIG, MIG and spot welding; PEM nuts, studs and standoffs pressed in. Welded assemblies are checked for squareness and for the mating dimensions that the machined parts depend on.

Finishing

Powder coating, plating, anodising and brushing — the same partner plants that finish our machined parts, so a housing and its lid come back in the same colour. Finishes →

Questions we get

Common questions

Why should I buy sheet metal from a machining shop?

Because your assembly usually has both. A machined housing with a bent cover and a laser-cut bracket is three purchase orders and three delivery dates if you buy them separately, and nobody owns the fit between them. With us it is one order, one inspection, one date — and if the parts do not fit each other, that is our problem.

Do you tell customers the sheet metal is subcontracted?

Yes — it is on this page and it is on the quote. We would rather lose a job than have a customer find out later.

What files do you need?

A STEP or DXF of the part plus a PDF drawing with material, thickness, bend directions and finish. If you only have the 3D model we will produce the flat pattern and send it back for approval.

What about tolerances?

Sheet metal holds looser tolerances than machining — typically ±0.1 – 0.2 mm on cut features and more on bends, depending on material and thickness. Where a sheet metal part has to locate against a machined one, we hold the machined part tight and design the sheet metal feature with clearance. We will say so on the drawing review.

Minimum quantity?

None. Laser cutting needs no tooling, so a single prototype bracket is a normal order.

Send the assembly, not just the bracket

If a sheet metal part goes with a machined one, send both drawings. We quote them together and check that they fit before either is made.
